How low can the temperature be and still provide heat? Also, what is the warranty?

The coldest the outdoor temperatures can be for this system to continue providing an efficient output of heat is 5°F before adding in supplemental backup heat kits. It can still continue to operate down to as low as -13°F, but the heat output will not be nearly as efficient as it would be at 5°F. If you need a system that can run at temperatures colder than 5°F, check out MRCOOL's Central Ducted Hyper Heat series (model number: CENTRAL-30-HP-C-230B00-O / MVP-30-HP-MUAH-230A00-O) and Universal series (UHP18030-O / UAH18030-O), which has 100% heat outputs at -5°F and -13°F, respectively.

The MRCOOL VersaPro heat pump systems have a 10 year warranty on both the compressor and part replacements. Online registration is required to receive the full benefits of the warranty.
